-
- Weiterhin bevorzugt sind symmetrische Azinpigmente der Formel (II), bei der die mit X und/oder die mit T markierten Ringe einen Substituenten aus der Reihe Methyl, Methoxy, Acetylamino, Benzoylamino, Carboxy, Carbamoyl oder Nitro tragen.
- Weiterhin bevorzugt ist das symmetrische Azinpigment der Formel
Die neuen Azinpigmente der Formel (1) sind dadurch erhältlich, daß man eine Verbindung der Formel mit einer Verbindung der Formel in Gegenwart von Hydrazin oder einer Hydrazin liefernden Verbindung wie Hydrazinhydrat oder einem Hydraziniumsalz umsetzt. In den Formeln (IV) und (IVa) haben T, T', X und X' die zu Formel (I) angegebenen Bedeutungen. - Dazu arbeitet man zweckmäßig in Wasser oder im organischen Lösungsmittel bei schwach sauren Bedingungen und erhöhter Temperatur, bevorzugt bei 50 bis 180°C. Geeignete organische Lösungsmittel sind Alkohole wie Methanol, Ethanol, Amylalkohol oder Glykolmonoalkylether; Aromaten wie Chlorbenzol, Nitrobenzol, Toluol; amidische Lösungsmittel wie Formamid, Dimethylformamid, N-Methylpyrrolidon oder Säuren wie Ameisensäure oder Essigsäure.
- Geeignete Säuren zur Herstellung der sauren Bedingungen sind anorganische wie Salzäure, Schwefelsäure oder Phosphorsäure bzw. organische wie Ameisensäure, Essigsäure, Chloressigsäure, Dichloressigsäure, Oxalsäure, Benzolsulfonsäure oder p-Toluolsulfonsäure.
-
- In den Formeln (V) und (Va) haben T, T', X und X' die zu Formel (I) angegebenen Bedeutungen; R bezeichnet Alkyl, vorzugsweise Cl-C6-Alkyl, insbesondere Methyl oder Aryl, insbesondere Phenyl.
- Die Verbindungen der Formel (IV) sind durch Umsetzung eines Isatosäureanhydrids der Formel (IV)

- Ein weiteres Herstellungsverfahren für die Pigmente der Formel (1) besteht in der Kondensation eines Hydrazons der Formel
mit einem Hydrazon der Formel im sauren Medium, wobei unter Abspaltung eines Mols Hydrazin die Pigmente der Formel (I) gebildet werden. Man arbeitet dabei zweckmäßig in organischen Lösungsmitteln bei erhöhter Temperatur, vorzugsweise bei 50 bis 180°C.

Die Feinverteilung kann auch durch Mahlen mit oder ohne Mahlhilfsstoffen wie anorganischen Salzen oder Sand, gegebenenfalls in Anwesenheit von Lösungsmitteln wie Toluol, Xylol, Dichlorbenzol oder N-Methylpyrrolidon erzielt werden. Farbstärke und Transparenz des Pigmentes können durch Variation der Nachbehandlung beeinflußt werden.

- b) In ein Gemisch aus 100 ml Dimethylformamid und 5 ml 96%iger Schwefelsäure trägt man 10 g des Hydrazons der Formel
ein und rührt 30 Minuten bei 130°C. Nach Absaugen und Trocknen erhält man so 4 g eines Gelbpigmentes, das mit dem nach Beispiel 1 a erhaltenen identisch ist. -
-
-
- 8 g feingemahlenes Pigment gemäß Beispiel 1 a werden in 92 g eines Einbrennlackes folgender Zusammensetzung dispergiert:
- 13% Alkydharz
- 15% Melaminharz
- 5% Glykolmonomethylether
- 34% Xylol
- 13% Butanol
- Als Alkydharze kommen Produkte auf Basis synthetischer und pflanzlicher Fettsäuren wie Kokosöl, Rizinusöl, Rizinenöl, Leinöl u.a. in Frage. Anstelle von Melaminharzen können Harnstoffharze verwendet werden.
- Nach erfolgter Dispergirung wird der pigmentierte Lack aus Papier-, Glas-, Kunststoff- oder Metallfolien aufgetragen und 30 Minuten bei 130°C eingebrannt. Die Lackierungen besitzen sehr gute Licht- und Wetterbeständigkeit sowie gute Überlackierechtheit.

Die Mischung kann entweder bei 220 bis 280°C direkt in einer Spritzgußmaschine verspritz oder in einer Strangpresse zu gefärbten Stäben bzw. auf dem Mischwalzwerk zu gefärbten Fellen verarbeitet werden. Die Stäbe bzw. Felle werden gegebenenfalls granuliert und in einer Spritzgußmaschine verspritzt.
- Die gelben Formlinge besitzen sehr gute Licht- und Migrationsechtheit. In ähnlicher Weise können bei 280 bis 300°C, gegebenenfalls unter Stickstoffatmosphäre, synthetische Polyamide aus Caprolactam oder Adipinsäure und Hexamethylendiamin oder die Kondensate aus Terephthalsäure und Ethylenglykol gefärbt werden.

Verwendung dieser Druckfarbe in Buch-, Licht-, Stein- oder Stahlstichdruck führt zu gelben Drucken ähnlicher Echtheiten. Verwendet man das Pigment zur Färbung von Bleckdruck- oder niedrigviskosen Tiefdrucktinten, erhält man orangefarbene Drucke ähnlicher Echtheiten.
